• Collaborate with cross-functional teams, including hardware engineers, and physicists, to design, test, and optimize software-hardware interaction
• Work closely with hardware teams to validate the correct behavior of software on physical systems and support troubleshooting during bring-up and operation
• Debug, profile, and optimize firmware to meet performance and scalability requirements
• Implement robust CI/CD pipelines for firmware updates, ensuring code quality and operational continuity
• Apply a strong foundation in data structures and algorithms to design efficient and optimized firmware solutions
• Document designs, processes, and methodologies to support knowledge transfer and regulatory compliance

Required skills:

• Bachelor’s degree in Computer Science and 4+ years of hands-on experience in software development
• Strong proficiency in Python, including web development with Flask and testing with tools such as pytest and test automation frameworks
• Solid front-end development experience using HTML, JavaScript, and libraries such as React
• Practical experience working with databases: MongoDB
• Familiarity with hardware communication protocols, real-time operating systems (RTOS), and programmatic interaction with hardware
• Experience using GitLab, issue tracking tools (e.g., Asana), and Sphinx for technical documentation
• Strong analytical and problem-solving skills with the ability to translate hardware requirements into robust software solutions
• Communicate fluently in English

We value:

• Master’s degree in computer science or electrical engineering
• Background in robotics/aviation/automotive
• Exposure to high-performance computing, quantum systems, or other advanced hardware technologies
• Experience in programmatic device control (SCPI, MODBUS, etc. over serial, USB, TCP)
• Experience in ARTIQ
• Experience in oscilloscopes, or emulators for software debugging

Compensation & Benefits:

• Competitive salary: We value our team members and therefore provide remunerations that reflect this, additionally rewarding achievements.
• Employee participation: Our team can share in the company’s success through an attractive Virtual Stock Option Plan (VSOP).
• Flexible working hours: We offer personal freedom through a variety of flexible work schedules.
